This invention relates to improvements in rubber menstruation band.

According to this invention, the const-ruction of the device is of a duplex nature in that it is composed of an outer rubber band which is thin and broad and an inner rubber band which is thicker and narrower than the outer band. The function of the outer band consists mainly in holding an absorbent matter, and preventing a sidewise slipping thereof,

and that of the inner band in exerting a pressure upon a mass of absorbent matter disposed inside it. The inner band is provided centrally and longitudinally of the outer band.

tion of exerting pressure, it is not subjected to any substantial tension. For this reason, its thickness need only be verysmall, which fact contributes to the comfort of the user. The inner band, which is much thicker than the outer band, preferably is apertured to give to the absorbent mass a suticient friction to prevent its dislocation.

Referring to the accompanying drawing, Figure 1 is a developed plan view of the menstruation band according to the invention.

Figure 2 is a cross sectional view taken along the line II-II of Figure 1.

along the line III- III of Figure 1 and viewed in the direction of the arrow.

Referring more particularly to the numerals on the drawing, 1 is the outer rubber band broad`enough to cover and hold from below the necessary amount of absorbent cotton. The rubber band 1 is plaited 'at the Y middle portion thereof, as at 2, along the edges, and is pasted from both sides witha 4 narrow folded band 3, as of rubber.

Centrally Aand longitudinally of the outer band 1 is provided an inner rubber band 4. This band 4 pi'eferably is made of pure 'and more resilient rubber and is of a shorter length than the central length of the outer band, so that when the device is applied on human body, with a mass of absorbent cotton inside it, it is principally this inner band that will hold the cotton tightly owing to the tension to which it is sub]ected, while the outer Since the outer band is relieved of the func-ly Figure 3 is a longitudinal section taken.

band 1 is substantially without tension and it simply acts as a sort of receptacle to hold a mass of cotton and prevent a sidewise slipping thereof. The inner band is preferably provided with a plurality of apertures 5 to prevent the dislocation of the mass of cotton.

Since it is the inner rubber band 4 but not the outer band that is called upon to exert any substantial pressure on .a mass of absorbent matter, the latter need only be very thin and soft, which fact also adds to the comfort of the user. In this manner, not only a sulficientA pressure upon a mass of cotton is assured, butpthe possibility of tearing of the outer rubber band is reduced to a minimum.

The two .rubber bands 1 and 4 are united by pasting or otherwise near the end portions, as to 6, and are connected to the terminal pieces 7 made of any appropriate material, such as fabric, and are provided with tightening ribbons 8 and the buckles 9.

What I claim is 1. A menstruation band comprising an outer rubber band and an inner rubber band disposed vcentrally and longitudinally of and substantially shorter than the said outer rubber band, the said inner band being provided with a plurality of irregularities for preventing the dislocation of the absorbent material.

2. A menstruation band comprising an outer rubber band an an inner rubber band disposed centrally and longitudinally of and substantially shorter than the said outer rubber band, the said inner rubber band being provided with a plurality of apertures for preventing the dislocation of the absorbent mass and being considerably thicker than the said outer rubber band.

In testimony whereof I affix my'signature.
